Use the given information to find the number of degrees of freedom, the critical values x{ and XÃ, and the confidence interval estimate of a. It is reasonable to assume that a simple random sample has been selected from a population with a normal distribution
Nicotine in menthol cigarettes 99% confidence; n = 25, s= 0.29 mg.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
